Farming applications

Water is a fundamental requirement to ensure the optimal health and productivity of farm animals such as cattle, chickens, sheep, and pigs. It is not only the quantity but also the superior quality of the water that influences the desired growth and performance of these animals.
Water used in farming can originate from diverse sources, including water wells, civil water networks, and occasionally from rivers and other surface sources. Each source provides unique characteristics that must be managed effectively.
Aside from water sourced from civil networks, which often contains free chlorine, other sources typically harbor high levels of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology proves to be the most effective method for mitigating these detrimental effects. Contaminated farm water should undergo technological treatment to drastically reduce harmful substances, safeguarding animal health and productivity.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has achieved an innovative leap forward with the creation of a new generation of reverse osmosis membranes. Utilizing groundbreaking polymer interface nano-self-assembly technology, we have surpassed the conventional barriers of reverse osmosis membrane development with two critical advancements:
Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our expert team has remarkably lessened the separation layer's thickness to a revolutionary three-fold reduction compared to the traditional polyamide thin film, previously restricted to 100 nm. This cutting-edge advancement dramatically boosts water flux, offering a remarkable enhancement in permeability.
Enhanced Performance: Through the integration of nanoparticles and innovative hydrophilic polymers, we have achieved unparalleled strides in membrane hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
When placed alongside traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four pivotal dimensions:
Self-Assembled Nanocomposite Films
By marrying nano-scale precision control with nano-doping modification, we craft ultra-thin, meticulously ordered separation layers through state-of-the-art polymer interface nanotechnology. This pioneering method transcends the conventional limitations of polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous refinement of the layer-by-layer self-assembly process, the thickness of the functional layer is expertly controlled, achieving a significant 3x reduction in comparison to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption,thus optimizing performance.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the traditional polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These advanced materials display extraordinary oxidation resistance, withstanding exposures to 10 ppm chlorine, and pH tolerance, maintaining stability across pH levels from 1 to 12.
Anti-Fouling Surface Engineering
